In this study we propose a novel precoding criterion based on the direct minimization of the SEP for quantized signals with constant envelope and PSK modulation. Unlike the existing MSEP designs [1]}, [2]}, [3]}, [4]}, [5]}, [6]} the proposed approaches allow for any PSK modulation order and phase quantization with any number of bits.
Using the proposed criterion and the one from [6]} this study develops optimal precoding techniques based on a sophisticated B&B algorithm and practical precoding methods based on GS.
